The worst idea ever probably won't be implemented.
As Digby said the other day, it's our job to freak out when these kinds of things are floated. And when we do, there are always sensible sober people who inform us that there's no way it could happen, or it would be okay if it did because it would be traded for something worthwhile, or it's just a shiny object to distract us from some other horrible thing, or...
And any of these things could true. But when the idea of increasing the Medicare eligibility age is floated, it's up to the rabid lambs of blogofascism to freak out about it. Because it really is the worst idea ever.
